The oxidation problem of color steel coil
A.color steel coil 1
As the use rate of color steel coils becomes more and more common, its quality is getting higher and higher.
Because of its characteristics and advantages, it is widely used by everyone.
In order for everyone to better apply, let’s understand the oxidation of color steel coils. What are the problems?
Color steel coils must be protected from oxidation during use, because oxidation is ugly at this time, and it is also a great loss to users.
The oxidized color steel coil can hardly be used, but how to prevent the color steel coil from oxidizing in the air?
The first is that the packaging should be carried out in terms of temperature and humidity,
so the humidity of the wooden shaft should not be greater than 18%,
and the temperature of the aluminum coil should not be greater than 45°C.
If you enter a high temperature and high humidity area from a low-temperature area, please do not open the sealed package immediately.
In order to allow time for the perforated net to adapt to these environments,
no perforated net should be installed where the roofs of workshops and warehouses are leaking rain or snow.
Strengthen air drying management, compressed air does not contain moisture.
Strengthen the management of rolling oil to keep the moisture content below 0.04%.
The packaging of the aluminum mesh sheet should seal, and each roll should fill with an appropriate amount of desiccant.
Reducing the contact of the surface of the punching net with air and moisture can prevent the oxidation of
the punching of the aluminum plate to a large extent, and play an important role in protecting the punching of the aluminum plate.
The color steel coil made of stainless steel punching and numerical control punching.
Due to the special stainless steel material, scratches sometimes appear when punching, which affects appearance and use.
To prevent this from happening, a thin plastic film can be coated on the stainless steel surface.
Film covering is a physical process, that is, a layer of film and a layer of an aluminum plate is laminate through high temperature
and high pressure.
The laminating process has many advantages.
It is not oxidized by air and humidity and can reduce the damage to the aluminum plate during the production process.
The above is about the oxidation of color steel coils.
You can understand that you can achieve good results by following the correct operation method during use.
If you don’t understand, you can call for a consultation, and we will give it according to your actual requirements.
You make reasonable suggestions to avoid unnecessary trouble in blind operation.
